2022-05-02syscalls: fork() noreap flagdzwdz
2022-05-02kernel/syscall: implement _syscall_close()dzwdz
2022-05-01kernel/proc: `process_handle_get` for safely accepting handle idsdzwdz
2022-05-01kernel/proc: make handles separate refcounted objectsdzwdz
2022-04-16kernel/vfs: refactor `vfs_request_accept` into `vfs_backend_accept`dzwdz
handling the backend queue makes more sense here than in the syscall implementation. it's also just overall cleaner
2022-04-16kernel/vfs: be more strict about the state of `vfs_backend.handler`dzwdz
2022-04-15kernel/vfs: don't hang on orphaned vfs callsdzwdz
2022-04-14kernel/proc: only change state through `process_transition`dzwdz
2022-04-14kernel: port init's `printf` implementationdzwdz
2022-04-12kernel: make all sizes unsigned, sort out the sign messdzwdz
2022-04-09kernel: prevent switching processes in syscall handlersdzwdz
2022-04-09kernel: `vfs_request_accept` now doesn't switch processesdzwdz
2022-04-07kernel/vfs: implement a vfs request queuedzwdz
2022-03-27init: userland tty emulator ; also workaround a fork() bugdzwdz
2022-03-27shared/syscalls: change some pointer types to void*dzwdz
2021-11-14shared: use a single implementation of mem* functions everywheredzwdz
2021-11-04Merge branch 'main' into fork2dzwdz
2021-11-03kernel: implement virt_cpy2kmallocdzwdz
2021-11-02fork2() refactor: implement fs_fork2()dzwdz
2021-11-02fork2 refactor: every process now has (only) a single controlled vfs_backenddzwdz
2021-10-04implement process_kill()dzwdz
2021-10-04remove support for processes returning strings on exitdzwdz
This isn't really all that useful, it doesn't enable anything that wasn't possible before. With it removed I'll be able to implement process_exit() in a much simpler way.
2021-09-23_syscall_mount(): ignore trailing slash in mount pathdzwdz
2021-09-22_syscall_open: strip the mount prefix in a better waydzwdz
2021-09-21refactor `await_finish` into `process_try2collect`dzwdz
the new name is terrible, but at least the function now has a clear purpose
2021-09-21make await() fail gracefully when callee has no alive children alreadydzwdz
2021-09-21add `__force` for marking casts across adress spacesdzwdz
2021-09-20create a few specialized panic()sdzwdz
thanks to this i can tell which ones are placeholders, and which ones should stay
2021-09-20add an offset parameter to read() and write()dzwdz
2021-09-20use a single struct for all fs_wait return valuesdzwdz
2021-09-19slightly tidy up some syscallsdzwdz
yay for pointless changes
2021-09-18_syscall_mount: actually use the just computed `backend` vardzwdz
whoops
2021-09-18implement NULL mountsdzwdz
2021-09-18merge `kernel/types.h` and `init/types.h`dzwdz
2021-09-16implement output from vfs callsdzwdz
2021-09-16fs_read stub, basic implementation in userlanddzwdz
2021-09-15fs_wait: pass the file ID toodzwdz
2021-09-14merge the `syscall_handler` and `_syscall` declarationsdzwdz
i think that making the call a bit more "transparent" makes the code nicer
2021-09-14add support for 4-parameter syscallsdzwdz
2021-09-12simplify `fs_respond`'s signaturedzwdz
2021-09-12allow vfs_request_finish to returndzwdz
thanks to this, the fs provider can continue executing until the next fs_wait() call. that should speed things up a bit
2021-09-12implement part of `fs_respond`dzwdz
2021-09-12barebones `memflag()` implementation - letting the user allocate pagesdzwdz
2021-09-12implement most of fs_waitdzwdz
awaited_req is a garbage name but i couldn't come up with a better one. i also have no idea how to handle all the failure states
2021-09-12vfs_request refactor pt2dzwdz
2021-09-12vfs request refactor pt1dzwdz
2021-09-12remove some dead codedzwdz
2021-09-12remove obsolete commentdzwdz
2021-09-11add some helper functions for copying between virtual and physical memorydzwdz
this was already possible, but now it's slightly safer
2021-09-11replace `user_ptr` with a linux-style `__user` annotationdzwdz
